Ethan Gannaway, 8, and his parents are suing the district, its superintendent, an elementary school principal and counselor.

The family said the boy was bullied and harassed on the playground by another student at Davis Elementary in September, and then faced retaliation from staff after reporting the incident.

The lawsuit claims Principal Jeff Kirby accused Ethan of lying, had him sit in a corner and repeat over and over "I will not lie."

"It got to the point where he was physically sick: vomiting, having nightmares, crying, scared of adults -- mentally sick, physically sick," said Mathew Gannaway, Ethan's father.

Mathew Gannaway said his son was born with a cyclic vomiting condition aggravated by the way the school administration treated him.

The lawsuit names Principal Jeff Kirby, Superintendent Todd Abrahamson and Counselor Nikki Tews. They are accused of bullying and professional negligence, for failing to prevent and participating in the bullying, harassment, intimidation, discrimination and retaliation against Ethan.

Mathew Gannaway said he is suing to prevent this from happening to any other child. The family discussed the lawsuit during a news conference on Tuesday.

"The damage didn't come from bullying on the playground. It came from the bullying by the principal, the counselor and the superintendent, calling him a liar," the family's attorney Roxanne Conlin said.

The Gannaway family decided to pull their three children out of the school district and now drive 100 miles per day back and forth to East Marshall schools instead.

KCCI contacted the district office for comment on the case. The superintendent had no comment.
